Description

Technical Field

[0001] This invention relates to the field of plastic cup processing equipment, and in particular to a cup body reversing and grouping mechanism. Background Technology

[0002] The processing of plastic cups typically begins with raw material preparation, where polypropylene (PP) or polystyrene (PS) granules are mixed with additives such as color masterbatch. The mixture is then melted and calendered into sheets of a specific thickness using an extruder, which are then wound into rolls. Next, the sheets are fed into a thermoforming machine, where they are heated and softened before being molded into the cup shape using vacuum or air pressure in a mold, simultaneously completing the cup rim trimming process. The molded cups are then decorated with surface printing or labeling as needed. Finally, they are automatically stacked, counted, and packaged using a stacking machine. Scrap materials generated during production can be recycled, crushed, and mixed with new materials for reuse.

[0003] However, existing equipment often encounters the following problems during use:

[0004] (1) In the prior art, when plastic cups need to be transferred via two vertically or parallel conveyor belts, traditional conveying mechanisms can only achieve continuous conveying and cannot perform intermittent grouping according to packaging or counting requirements. This defect causes plastic cups to continuously accumulate at the track-changing node during production line operation, resulting in mutual squeezing, deformation, and even breakage of the cups. At the same time, due to the lack of a grouping mechanism, subsequent counting and packaging processes must rely on manual intervention for sorting and arrangement, which not only significantly reduces production efficiency but also increases labor costs and defect rate. In addition, the inability to achieve intermittent grouping means that the entire production line must frequently start and stop to adapt to the track-changing rhythm. This start-stop shock will accelerate equipment wear and shorten equipment life.

[0005] (2) In some existing pushing mechanisms, after completing one cup push, the booster component needs to return to its initial position along the original path to perform the next push. However, since the first conveyor belt usually runs continuously, new cups are continuously transported to the track-changing area. During the return process of the booster component, if it fails to effectively avoid these continuously transported next set of cups, it will directly interfere with the cups mechanically, causing the cups to be knocked over, jammed, or deviated from the conveyor track. This interference will not only cause large-area damage to the cups, but also easily cause blockage and jamming accidents of the conveyor belt, forcing the production line to be interrupted for manual cleaning and adjustment. Frequent shutdowns for cleaning not only seriously reduce production efficiency, but also increase the maintenance burden and operating costs of the equipment, and may even cause more serious equipment failures due to cup fragments entering the transmission system. Summary of the Invention

[0006] The main objective of this invention is to provide a cup-body track-changing grouping mechanism, which solves at least one of the aforementioned problems to a certain extent.

[0022] A roller, which is mounted on one side of the fixed base;

[0023] A cam rail is provided on the roller surface and is slidably connected to the bottom end of the tilting frame.

[0024] A drive motor, the output end of which is connected to the roller.

[0025] Also includes:

[0026] A drive shaft is mounted on one side of the sliding base in an extending direction;

[0027] A first link, one end of which is connected to one end of the sliding base;

[0028] The second link has one end movably connected to the other end of the first link, and the connection point between the first link and the second link is the drive shaft;

[0029] A transverse link, one end of which is slidably connected to the other end of the second link;

[0032] The first force-applying rod, one end of which is connected to the top end of the booster shaft;

[0033] The second force-applying rod has one end movably connected to the other end of the first force-applying rod.

[0034] Also includes:

[0035] The first guardrail, one end of which is connected to one side of the sliding base;

[0036] The second guardrail, one end of which is connected to the other side of the sliding base;

[0037] A first conveyor belt is located on one side of the fixed base, and the first conveyor belt is parallel to the guide rail.

[0038] A second conveyor belt is located on one side of the first conveyor belt;

[0039] A baffle, the baffle being located in the extending direction of the first conveyor belt and the baffle being installed at the other end of the first guardrail;

[0040] The guide plate is provided in two places, which are arranged side by side, and the top of the two guide plates are connected to the other end of the second guardrail.

[0047] Compared with the prior art, the beneficial effects of the present invention are:

[0048] (1) This invention achieves intermittent group pushing by converting the continuous rotation of the booster motor into the reciprocating linear motion of the top slide plate: the eccentrically connected push wheel drives the main force rod, which drives the top slide plate to slide along the top slide rail perpendicular to the conveyor belt, so that the booster plate pushes only a small group of cups accumulated between the baffle and the guide plate laterally into the second conveyor belt each time. By controlling the motor speed to match the feeding speed of the first conveyor belt, the pushing rhythm and the number of groups are controllable, which fundamentally solves the problems of continuous accumulation and deformation of cups at the track change node, as well as the low efficiency and equipment wear caused by relying on manual sorting.

[0049] (2) The design incorporates a cam lifting and avoidance mechanism: the drive motor rotates the roller with the cam rail, and when its protruding section contacts the tilting frame, it forces the tilting frame to lift the lifting rod, thereby raising the booster rod and the booster plate together; so that the booster plate passes over the new cup body during the return stroke, and then falls back to the working height after the roller rotates to the concave section. This "push-lift-return-lower" cycle completely eliminates the hidden dangers of return stroke impact, cup body jamming and conveying interruption, ensuring the continuity and stability of the track changing process.

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0059] like Figure 1-5 As shown, the present invention provides a cup body track changing grouping mechanism, which includes a fixed base 1, a guide rail 2, a sliding base 3, a top slide rail 4, a top slide plate 5, a push rod 6, a push plate 7, and a push wheel 8.

[0060] The fixed base 1 provides a stable support foundation for the entire mechanism, ensuring that the components maintain relative positional accuracy during operation. The guide rail 2 is arranged laterally on the top surface of the fixed base 1. This design guides the sliding base 3 to perform lateral linear movement, ensuring that the sliding base 3 can slide smoothly under the drive of the push wheel 8. The sliding base 3 is slidably connected to the guide rail 2. The sliding base 3 supports the top slide rail 4 and the top slide plate 5 on it, etc., and realizes the initial displacement transmission of the track-changing action through its lateral movement. The top slide rail 4 is installed on the top surface of the sliding base 3, and the top slide rail 4 is perpendicular to the guide rail 2. The top slide rail 4 guides the top slide plate 5 to slide perpendicular to the direction of the guide rail 2, thereby realizing the lateral pushing path of the booster plate 7 between the two conveyor belts.

[0061] In this invention, the top slide plate 5 is slidably connected to the top slide rail 4. The top slide plate 5 is used to connect the push rod 6 and transmit thrust. Simultaneously, its sliding on the top slide rail 4 drives the push plate 7 to achieve a reciprocating pushing action. One end of the push rod 6 is rotatably connected to both sides of the top slide plate 5. This design converts the sliding of the top slide plate 5 into the swinging or translating motion of the push plate 7. The rotatable connection also accommodates the angle changes of the push plate 7 at different positions. The push plate 7 is installed at the other end of the push rod 6. The push plate 7 is located between the baffle 28 and the guide plate 29. The push plate 7 is used to directly contact the plastic cup and push it from the first conveyor belt 26 into the second conveyor belt 27. Its positional design ensures accurate action on the cup being processed by the baffle 28 and the guide plate 29.

[0062] In this invention, the push wheel 8 is arranged laterally on the top surface of the fixed base 1. The push wheel 8 is used to convert the rotational motion of the booster motor 10 into the reciprocating push-pull action of the main force rod 9. It is the core power conversion component that drives the reciprocating motion of the sliding base 3. One end of the main force rod 9 is connected to the wheel surface of the push wheel 8, and the other end of the main force rod 9 is connected to one side of the top slide plate 5. The main force rod 9 is used to transmit the push force of the push wheel 8 to the top slide plate 5. At the same time, the reciprocating sliding of the top slide plate 5 is realized through its eccentric connection with the push wheel 8. The output end of the booster motor 10 is connected to the central axis of the push wheel 8. The booster motor 10 provides power for the entire reciprocating motion. The pushing frequency can be adjusted by controlling its speed. The top end of the lifting rod 11 is connected to one side of the booster rod 6. The lifting rod 11 is used to lift the booster rod 6 when the booster plate 7 returns, so as to avoid interference with the cup to be pushed during the return.

[0063] In this invention, the tilting frame 12 is a triangular frame, with one end of the tilting frame 12 movably connected to one side of the fixed base 1; the top end of the tilting frame 12 is connected to the bottom end of the lifting rod 11; the tilting frame 12 is used to convert the rotational motion of the roller 13 into the lifting motion of the lifting rod 11, and its triangular structure can ensure the stability of the lifting process. The roller 13 is installed on one side of the fixed base 1; the roller 13 is used to support the cam rail 14 and drive the tilting frame 12 to lift and lower through rotation, and is a key component for controlling the lifting action of the booster plate 7. The cam rail 14 is opened on the surface of the roller 13, and the cam rail 14 is slidably connected to the bottom end of the tilting frame 12; the cam rail 14 is used to convert the continuous rotation of the roller 13 into the intermittent lifting and lowering of the tilting frame 12, and realizes the lifting of the booster plate 7 during the return stroke and the lowering during the push stroke through its concave and convex trajectory. The output end of the drive motor 15 is connected to the roller 13; the drive motor 15 provides power for the rotation of the cam rail 14, and works in coordination with the booster motor 10 to ensure the timing coordination of the pushing and lifting actions;

[0064] In this invention, the drive shaft 16 is installed on one side of the sliding base 3 in an extending direction. The drive shaft 16 is used to convert the linear motion of the sliding base 3 into the swing of the first link 17 and the second link 18, and is the hub for motion transmission. One end of the first link 17 is connected to one end of the sliding base 3. The first link 17 is used to transmit the displacement of the sliding base 3 to the second link 18, and is the starting link for motion conversion. One end of the second link 18 is movably connected to the other end of the first link 17. The connection between the first link 17 and the second link 18 is the drive shaft 16. The second link 18 is used to change the direction of motion and transmit power to the transverse link 19 to realize multi-stage motion conversion. One end of the transverse link 19 is slidably connected to the other end of the second link 18. The transverse link 19 is used to convert the swing of the second link 18 into the rotation of the flipping rod 20, and its slidable connection can compensate for angle changes during motion.

[0065] In this invention, one end of the flipping rod 20 is movably connected to the other end of the transverse connecting rod 19; the flipping rod 20 is used to convert the displacement of the transverse connecting rod 19 into the rotation of the booster shaft 21, thereby realizing the final transmission of the boosting force. The booster shaft 21 is installed at the other end of the flipping rod 20; the booster shaft 21 is used to connect the first force-applying rod 22 and transmit the rotation of the flipping rod 20, and is the final force-applying point for driving the top slide plate 5. One end of the first force-applying rod 22 is connected to the top end of the booster shaft 21; the first force-applying rod 22 is used to transmit the rotation of the booster shaft 21 to the second force-applying rod 23, and is the intermediate link of force transmission. One end of the second force-applying rod 23 is movably connected to the other end of the first force-applying rod 22; the other end of the second force-applying rod 23 is movably connected to one side of the top slide plate 5; the second force-applying rod 23 is used to finally transmit the movement of the first force-applying rod 22 to the top slide plate 5, driving the top slide plate 5 to slide along the top slide rail 4;

[0066] One end of the first guardrail 24 is connected to one side of the sliding base 3; the first guardrail 24 moves with the sliding base 3 to guide the cups on the first conveyor belt 26 and to position the cups in conjunction with the baffle 28. One end of the second guardrail 25 is connected to the other side of the sliding base 3; the extended ends of the first guardrail 24 and the second guardrail 25 face the first conveyor belt 26; the second guardrail 25 moves with the sliding base 3 to connect to and drive the guide plate 29 to move, thereby guiding and organizing the cups. The first conveyor belt 26 is located on one side of the fixed base 1, and the first conveyor belt 26 is parallel to the guide rail 2; the first conveyor belt 26 is used to continuously transport the plastic cups to be grouped and is the main feeding channel. The second conveyor belt 27 is located on the other side of the sliding base 3. The first conveyor belt 26 is located on one side; the second conveyor belt 27 is used to receive the plastic cups pushed by the pusher plate 7 to realize the group transfer of the cups. The baffle 28 is located in the extension direction of the first conveyor belt 26 and is installed at the other end of the first guardrail 24. The baffle 28 is located on one side of the two guide plates 29. The baffle 28 is used to block and position the cups conveyed from the first conveyor belt 26 so that they are in the correct position before being pushed. There are two guide plates 29, which are arranged side by side and the top of the two guide plates 29 are connected to the other end of the second guardrail 25. The two guide plates 29 are used to guide the cups pushed out from the baffle 28 to smoothly enter the second conveyor belt 27, while preventing the cups from tipping over or shifting during the pushing process.

[0067] It should be noted that, in the cup-body variable track grouping mechanism designed in this invention, when the first conveyor belt 26 transports a row of plastic cups, two motors are simultaneously activated. The booster motor 10 starts, and the rotation of the output end of the booster motor 10 drives the push wheel 8 to rotate. When the push wheel 8 pushes the main force rod 9 towards the sliding base 3, the sliding base 3 slides linearly on the guide rail 2. The displacement of the sliding base 3 drives one end of the first connecting rod 17 to rotate, thereby causing the drive shaft 16 to rotate. The rotating drive shaft 16... This causes the second connecting rod 18 to flip, which in turn pushes the transverse connecting rod 19 to shift, causing the flipping rod 20 to rotate. The booster shaft 21 then rotates accordingly, pushing the first force-applying rod 22 and the second force-applying rod 23. This causes the top slide plate 5 to slide linearly under the guidance of the top slide rail 4. As a result, the booster rod 6 above the top slide plate 5 is pushed out. The pushed-out top slide plate 5 uses the booster plate 7 to push a small group of plastic cups, which are being transported between the baffle 28 and the guide plate 29, onto the second conveyor belt 27. When the push wheel 8 pulls the main force-applying rod 9 away from the sliding base 3, the above process is reversed until the booster rod 6 above the top slide plate 5 returns to its original position. The continuous rotation of the push wheel 8 constitutes the reciprocating motion of the sliding base 3 and the booster rod 6. As the sliding base 3 reciprocates, the first guardrail 24 and the second guardrail 25 are also driven together, causing the baffles 28 and guide plates 29 at their respective ends to reciprocate together. The movement of the baffles 28 and guide plates 29 guides the conveyed plastic cups neatly one by one. During the return process, the drive motor 15 starts and drives the roller 13. When the roller 13 rotates to the protruding section of the convex rail, the flipping frame 12 is lifted and rotates around the connection end with the fixed base 1 until the lifting rod 11 lifts the push rod 6. In this way, during the return process of the push plate 7, the push plate 7 will completely bypass the conveyed cup. When the roller 13 rotates to the concave rail of the convex rail, the push plate 7 will push it out again, thus forming a cycle.

[0068] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
